Bad graphics?http://apps.cocreate.com/OneSpaceModelingPE/Sec

Though the program is compatible with Vista, and my system has all compatible graphics, when i create shapes they do not appear on my screen until i change the camera angle etc, making it difficult to use the software as i cannot see, for example, what i am selecting, extruding or shelling Is this normal? Is there a way of fixing it? Thanks, Lauren
